Description

The present invention relates to a temporary assembly structure of a shape member in the case of producing a frame (mounting frame) for a machine device, for example, using a shape member such as a square pipe.

In the case of manufacturing a frame by connecting the shape members, if the shape members are joined while being positioned one by one, the number of manufacturing steps increases and the manufacturing efficiency decreases. For this reason, in the manufacture of the frame, for example, a temporary assembly structure of the shape members is formed using a connector so that the shape members are connected at a predetermined position. The shape accuracy of the frame is affected by the shape accuracy of the temporary assembly structure. For this reason, when high shape accuracy is required for the temporary assembly structure, as described in Patent Document 1, the formation of the temporary assembly structure is performed on the temporary assembly base.

JP-A-7-62875

Here, it is necessary to perform joining of each shape member constituting the temporary assembly structure while removing the connecting tool from the shape member, and there is a problem in that the efficiency of the joining work is reduced. In addition, when the temporary assembly structure formed on the temporary assembly base is moved to another location to join the shape members, the temporary assembly structure may be displaced due to vibration or its own weight during movement. There is a problem that the shape accuracy is lowered due to deformation. On the other hand, in order to prevent the displacement between the temporary assembly structures and the deterioration of the shape accuracy of the temporary assembly structure due to the movement of the temporary assembly structure, the period during which the temporary assembly base is occupied by joining on the temporary assembly base As a result, the problem arises that the production efficiency of the temporary assembly structure decreases.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a temporary assembly structure of a shape member having a high shape accuracy without using a temporary assembly base without being held by a connector.

Has been. In addition, the first and second projecting portions 22 and 23 projecting opposite to each other at two different positions on the end portion of the profile body 21, for example, the center of the opposite sides of the end portion of the profile body 21. Is formed.

Here, the 1st, 2nd protrusion parts 22 and 23 are trapezoid shape by side view. The first and second projecting portions 22 and 23 are formed such that one projecting portion (for example, the first projecting portion 22) is long in front view. On the other hand, the first and second engagement holes 25 into which the first and second projecting portions 22 and 23 are fitted in the joint portions where the end portions of the square pipe 19 are joined at the side portions of the square pipe 20. , 26 are formed. The first and second projecting portions 22 and 23 and the first and second engaging holes 25 and 26 are formed by laser cutting by positioning based on a manufacturing drawing or the like. Accordingly, the first and second projecting portions 22 and 23 and the first and second engaging holes 25 and 26 with high dimensional accuracy can be easily obtained.
The first and second projecting portions 22 and 23 may be rectangular when viewed from the side, and chamfered at both side ends.

From the above configuration, in the temporary assembly structure Q of the shape member, the first and second projecting portions 22 and 23 formed at the end portion of the square pipe 19 are formed at the side portions of the square pipe 20. Since the square pipes 19 and 20 can be accurately positioned and temporarily assembled without using a connector or the like, the temporarily assembled square pipes 19 and 20 can be fitted to each other. Can be prevented from shifting or rotating. Further, since the first and second projecting portions 22 and 23 are trapezoidal when viewed from the side, the first and second projecting portions 22 and 23 are respectively formed in the first and second engaging holes 25 and 26. Can be easily fitted. And when the 1st, 2nd protrusion parts 22 and 23 are viewed from the front, since the length of one protrusion part (for example, 1st protrusion part 22) is formed long, the side which the square pipe 19 joins It is possible to easily select the end portion.
